An arrow is fired at a target on a high wall. How does the energy change between the moment the arrow is fired and the moment il
hits the target?
The potential energy and kinetic energy remain the same.
The potential energy decreases as kinetic energy increases.
The kinetic energy decreases as potential energy increases.
The kinetic energy remains at zero, but potential energy increases.
